STANDARD-SUPPORT FOR CLOTH-CUTTING MACHINES- To all whom it may concernBe it known that I, HYM'AN MAIMIN, a citizen of the United States,residing in the borough of Manhattan, city, county, and State of NewYork, have invented certain new and useful Improvements inStandard-Supports for Cloth-Cutting Machines; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

In cloth cutting machines of the type herein referred to, greatdifiiculty is encountered in adequately securing the standard of themachine to the base plate. The reason for this is that the standard,carrying at its upper end the heavy motor frame and motor, is subjectedin operation to very severe vibrations and these vibrations tend toloosen the connection between the standard and the base plate. Thisconnection is ordinarily efiected by means of screw threads on the lowerextremity of the standard cooperating with corresponding screw threadsin the base plate. The effect of the vibrations is to so far mutilatethe screw threads as to loosen the standard, permitting the edge of theknife, which is carried by the standard, to depart from the straightline of cut and to strike against the edges of the throat in-thethroat-plate which is secured to the base plate in front of thestandard. This necessitates the substitution of a new standard atconsiderable eX- pense.

The object of the present invention is to overcome these diilicultiesand this is accomplished by insertingbetween the base plate and thestandard a nest plate, so shaped that it will receive the throat plateas well as the base of the standard. so that complete registry betweenthe knife guide in the standard and the throat plate is assured.

The preferred form of the invention is illustrated in the accompanyingdrawing, in which I Figure 1 shows the standard inside elevation withthe nest plate likewise in side elevation and mounted in the base platewhich is shown in section; Fig. 2 is a like front elevation; Fig. 3 is aside elevation partly in section showing the nest plate in section; Fig.4 isa section on line 44 of Specification of Letters Patent.

Fig. ,3, and Fig. 5 shows the nest plate, the two-part throat plate, andthe base of the standard.

The standard 1, which may beof any suitable construction, has anextended base 2 in the form of two sectors 3 and 4, of such shape'as tofit, with the base 2, into the nest plate 5 (see Figs. 4c and 5). The 1standard is secured to the nest plate byv the upwardly extending screws6 passing through the nest plate and into the base'of the standard.plate are secured to the nest plate by the screws 7. The outer peripheryof the nest plate 5 is screw-threaded, as shown in Figs. 1, 2 and 3, andthese screw threads engage corresponding screw threads in a recess inthe base plate.

The arrangement permits the making of the nest'plate of a hard steelwhich is not suitable for the standard, and it also makes possible theready removal of the connection between the standard and the base plate.If the engaging screw threads are destroyed by the vibrations, a newnest plate can be substituted for the old. If necessary, the new nestplate may be of slightly larger diameter than the old and new threadsmay becut in the recess in the base plate.

' By mounting the throat plate in the nest plate, all possibility of adisturbance of the throat plate in the nest plate in front 0 thestandard.

2. A standard for a cloth cutting machine, in combination with a nestplate set into the base plate of the machine and screws extendingupwardly through the nest plate into the base of the standard to securethe standard to the nest plate, and.

a throat plate in the nest plate in front of the standard. 7
